Hey all, I've put together a quick and dirty mod using an altoids tin with an 18650 batt and a small bottom feeding vial. For the most part it works fine, good vapor and the battery is lasting for 2 or 3 days. My issue with it is the liquid leaks through the connector hole back down into the box. Not a lot but after a couple weeks using it its getting messy inside. I can see a few ways to seal it better but I'm afraid I won't be able to remove the vial for refilling. I'm wondering if this is a typical problem with bottom feeders or has anyone else found a solution?
